Answer:
x =
Step-by-step explanation:
Given
= - 4
Multiply both sides by 5
3ax - n = - 20 ( add n to both sides )
3ax = - 20 + n = n - 20
Isolate x by dividing both sides by 3a
x =
The way to do is is to write down expression, find factors of each polynomial and than cancel as many as possible. What remains is our simplified version of starting expression.
We start with this:
Now we factor every polynomial
now we can cancel fallowing factors:
5x-3, x-1 and x+5
after that we left with:
20 Degrees

The pattern is mutiplying each time by 3 so the 6th figure would be 18 because 3×6=18
